Local PDF compressor
Select a PDF or drag it into the compressor. The tool reads the file and shows its page count and original size.
Use Preserve text to keep searchable text and PDF features, or Smaller file for image-based compression.
When using the stronger mode, choose the image quality that balances readability and output size.
Run compression, compare the original and output sizes, and download the result when it is smaller.
Some PDFs are already optimized or mostly contain efficiently compressed content. The tool will tell you when a new file would not be smaller instead of downloading a worse result.
Preserve text optimizes the PDF structure while retaining searchable text, vectors, links and forms. Smaller file renders pages as compressed images and usually reduces more data.
No. Image-based compression removes selectable text, links, forms and other interactive PDF content. Use Preserve text when those features matter.
Yes. In Smaller file mode, the quality control lets you trade image clarity for a potentially smaller output.
No. Both compression modes process the document locally in your browser.
